Optitop 150/40/80C -100

Siemens/Varex Optitop 150/40/80C -100 tube replacement for Radiographic system
Optitop 150/40/80C -100 P/N: 4802349 (Siemens Multix TOP, Polydoris ITS)

The Siemens Optitop 150/40/80C-100 (P/N 4802349) is a general-purpose radiographic/fluoroscopic (R&F) X-ray tube.

Key specs:

• Voltage rating: 150 kVp
• Power rating: 40kW/80kW (dual focus)
• Target angle: 12°
• Focal spots: 0.6–1.0mm
• Stator: 3-phase
• Nomenclature: “150/40/80C-100” indicates 150kVp, 40/80kW dual focal spot power, “C” housing/cooling variant, “-100” suffix

System compatibility:
Fits multiple Siemens R&F platforms — the model is listed under several system families: it fits SIRCOPE, SIREGRAPH, POLYDOROS, SIRESKOP, YSIO, AXIOM, and MULTIX systems. It’s specifically cross-referenced to the Multix TOP and Polydoros ITS platforms.

Note: there’s a closely related sibling part, the Optitop 150/40/80HC-100 (different P/N, e.g. 3345209), which has a 90° horn/different housing configuration — worth double-checking you have the “C” (not “HC”) variant confirmed, since Siemens tube housings in this family aren’t always interchangeable across the C/HC/H suffix.
